As long as the egoic mind is running your life, you cannot truly be at ease; you cannot be at peace or fulfilled except for brief intervals when you obtained what you wanted, when a craving has just been fulfilled. Since the ego is a derived sense of self, it needs to identify with external things. It needs to be both defended and fed constantly. The most common ego identifications have to do with possessions, the work you do, social status and recognition, knowledge and education, physical appearance, special abilities, relationships, personal and family history, belief systems, and often also political, nationalistic, racial, religious, and other collective identifications. None of these is you.
Do you find this frightening? Or is it a relief to know this? All of these things you will have to relinquish sooner or later. Perhaps you find it as yet hard to believe, and I am certainly not asking you to believe that your identity cannot be found in any of those things. You will know the truth of it for yourself. You will know it at the latest when you feel death approaching. Death is a stripping away of all that is not you. The secret of life is to "die before you die" - and find that there is no death.
